Mono Sulfur Silane Crosile®966 for high loading Silica tire

Crosile®966 Mono Sulfur silane Coupling agent

Physical Properties:

Crosile-996 is a Mono Sulfur silane that can reduce rolling resistance while maintaining wet traction. Compared to conventional silane coupling agents like Crosile-69 and Crosile-75;Crosile-996 offers superior processing performance and can improve the overall production efficiency of tires.

Applications and Performance

Crosile®-996  High-performance organosilane for silica rich tire tread compounds

A single-step, eco-friendly silane that unlocks ultra-low rolling resistance, winter-grade elasticity and class-leading wet traction in high-loading silica formulations.

1.Lower Rolling Resistance – verified

• Generates a strong filler–rubber network (enhanced Payne effect)  
• Drops tan δ 50–60 °C by 15–25 % → ≥ 4 % reduction in RRC (rolling-resistance coefficient)  
• One-shot addition eliminates multi-step mixing, cutting VOC emissions and energy use

2. Winter & Wet Performance – retained

• Dynamic modulus advantage from –20 °C to +10 °C → shorter braking on cold/wet roads  
• tan δ @ 0 °C kept high enough to preserve wet grip while fuel-saving

3.Processing Efficiency – boosted

• Acts as internal silica dispersant → 10–15 % lower Mooney viscosity  
• Shortens mixing cycles, improves extrusion surface, reduces die-build-up  
• Compatible with ≥ 80 phr silica without loss of scorch safety

Target application

Passenger-car green tires, all-season & winter compounds, HP/UHP segments – any tread stock demanding < 7 kg t-1 CO₂ savings with A-grade wet grip.
